While its a long shot for this to happen, its certainly something the NBA needs to consider before the lack of competition hurts their brand. Fans want to see the best product on the floor. The new format would allow more balance in post-season competition, not allowing the East best to walk into the Finals while the Western Conference beat each other down. And if your argument is traveling for east vs west match ups, considering they do that for 82 games its not a stretch.
